Abstract

Electric machine has at least one coil with ends of the coil wire fixed to separate connection elements. The connection elements are provided with a relatively thick soft-solder layer of at least approximately 30μ thickness. The soldered connection between an end of a coil wire and a connection element can be made by means of a laser.
